It delivers 44 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 70 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance schedule for oil changes. The 94 % efficiency means only 6 % of input power is lost to friction and windage, which keeps thermal rise manageable in continuous-duty cycles. ## Torque, backlash, and load ratings that govern the fit Continuous output torque is 44 N.m (389.4 lbf.in) at 100 rpm and 30 °C; maximum output torque reaches 70 N.m (619.6 lbf.in) for intermittent peaks. The 20 arc.min maximum torsional backlash is typical for a commercial-grade planetary stage — acceptable for positioning where cumulative error across multiple rotations is not critical, but too loose for a zero-backlash servo axis. Maximum axial force (Fa) on the output shaft is 450 N for the full 30,000-hour life, or 600 N if you accept a 10,000-hour service life. Radial force (Fr) is 340 N at mid-shaft for 30,000 hours, or 500 N for 10,000 hours. These limits drop with speed — the ratings are quoted at 100 rpm; higher speeds reduce allowable overhung load. Torsional rigidity is 2.5 N.m/arcmin, meaning each Newton-metre of load twists the output shaft by 0.4 arcmin. For a positioning application, multiply the peak torque by this stiffness to estimate windup at the load. ## Obsolete — sourced through independent channels Schneider Electric lists the GBX0600121004F as obsolete. No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The gearbox carries a shaft output IP54 rating — protected against dust ingress and splashing water, but not submersion. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not freezer or high-temp washdown zones.","metaTitle":"Schneider Electric GBX0600121004F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0600121004F planetary gearbox, 60 mm diameter, 12:1 reduction, 44 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"58 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"12:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"2.5 N.m/arcmin","Maximum output torque":"619.6 lbf.in (70 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"450 N 100 rpm, during 30000 hour at 30°C 600 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"340 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 500 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"389.4 lbf.in (44 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"2.4 in (60 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"20 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/9ea153871c508ff4012e07af813cee0e.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0600121004F/gearbox-with-straight-teeth-gbx-ø-60-mm-reduction-121-20arcmin-44-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0600121004F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0600121004F?","answer":"Continuous output torque is 44 N.m (389.4 lbf.in) at 100 rpm and 30 °C.
